Objective To summarize and explore the clinical value of selective partial neurotomy of muscular branch of triceps in the treatment of spastic talipes equines.Methods Forty-two cases were included in our study from Aug.2000 to Des.2007,all these cases accepted the operation of selective partial neurotomy muscular branch of triceps.In this study,29 cases were male,13 cases were female.Muscle force of legs,muscular tension,pathologic reflex,gesture and function of legs after operation were compared with that of before operation.Results The mean fallow-up was 18 months.During the fallow-up of this study,muscular tension degraded,the function of ankle joints and the gesture of extremitas inferior were improved obviously.The effective power was about 90% after 12 months follow-up.Conclusions Selective partial neurotomy of muscular branch of triceps is a effective method for the treatment of spastic talipes equines.The operation procedure is simple and effective,and could be generalized in the primary level hospital.

Tissue factor(TF)is the most important factor in the physiological coagulation process.TF also plays important roles in tumor growth,angiogenesis,invasion and metastasis by combining with factor VII.In recent years,targeted therapy for the TF has made remarkable progress,showing its significant inhibition of tumor tissue and metastasis.

Objective To evaluate the clinical diagnosis of gastric stromal tumors and the safety and feasibility with laparoscopic wedge resection.Methods The clinical data of diagnosis and treatment were retrospectively analyzed in 43 cases diagnosed as gastric stromal tumors by endoscopyic ultrasonography.Results Thirty-six cases were successful by laparoscopic surgery success rate being 83.7%.Endoscopic ultrasonography diagnosis rate was 69.0%.The positive rate of CD117 and CD34 in postoperative diagnosis of gastrointestinal stromal tumor wasl00%.The mean post-operative hospital stay was 5 days.Conclusion Endoscopyic ultrasonography can be selected as a main method for clinical diagnosis of gastric stromal tumors and laparoscopic resection was safe and feasible.

Objective To investigate the diagnosis and treatment of mesenteric fibromatosis.Methods We analyzed retrospectively the clinical data including clinical manifestation,treatment and follow-up results of the mesenteric fibromatosis in 11 cases.ResultsNine patients presented with abdominal mass.Two cases were found during other operation occasionally.Before operation,3 cases were misdiagnosed as leiomyosarcoma,1 case as malignant neurilemmoma,1 case as lymphoma.All patients were underwent surgical resection,and were diagnosed as mesenteric fibromatosis by pathology.Following-up,from 7 months to 72 months,2 cases relapsed.Conclusions The clinical feature of mesenteric fibromatosis is nonspecific.It is difficult to make correct diagnosis preoperatively.Surgical resection is the first choice for cure of patients with mesenteric fibromatosis.

Objective To investigate histopathological change of axillary lymph nodes and ecto-node encroachment of breast cancer following neoadjuvant chemotherapy in locally advanced breast cancer.Methods Second Hospital Affiliated to University of South China had received 86 patients with breast carcinoma from June 2002 to August 2009,these patients suffered lump over 5 cm and homonymy nonfusion lymphadenectasis.All samples were grouped on the basis of wether or not accept neoadjuvant chemotherapy.The first group included 46 patients,who were reluctant to receive neoadjuvant chemotherapy,operated after pricking pathological diagnosis.There were 40 patients with metastatic axillary lymph nodes and 17 patients with axillary ecto-node encroachment in the first group.The second group included 40 patients,who were voluntary to receive neoadjuvant chemotherapy,and operated after pricking pathological diagnosis and received three cycles of neoadjuvant chemotherapy on average.There were 26 patients with metastatic axillary lymph nodes and 6 patients with axillary ecto-node encroachment in the second group.Results The rate of metastatic axillary lymph nodes was 86.9% and the rate of axillary ecto-node encroachment was 36.9% in the first group,while 65% and 15% respectively in the scond group.There were significant deference in the rate of metastatic lymph node and axillary ecto-node encroachmen between two groups.Conclusion Neoadjuvant chemotherapy is effective to treat metastatic lymph node and axillary ecto-node encroachment in breast cancer.

Objective To study the application of cyctic duct dilatiion in bile duct exploration through the cystic duct by laparoscope combined with choledochoscope.Methods LC + laparoscopic transcyctic common bile duct exploration were performed in gallstones combined choledocholithiasis in 70 cases.The dilation of cyctic duct was performed by gas-baloon or metal dilator in 39 cases.The dilation of cyctic duct was not performed in 31 cases.Results There was one case of bile leakage and one case of cystic duct damaging in cystic duct dilation group.One case was found bleeding in abdomen postoperation in non-dilation group.Abdominal drainage was(60 ±11)mL and(55 ±8)mL in dilation group and non-dilation group,respectively.Conclusions The dilation of cyctic duct is simple and safe to create the tunnel for common bile duct exploration through the cystic duct by choledochoscope.

Nuclear receptors,the superfamily of ligand-activated transcription factors,play crucial role in the regulation of gene expression of the lipid metabolism,and are involved in many metabolic diseases,such as cholesterol gallstone disease.Recently many domestic and foreign researches on the role of nuclear receptors in the lipid metabolism,help to further elucidate the biomolecular pathogenesis of cholesterol gallstone disease and other diseases associated with the lipid metabolism.

Biliary tract malignant tumours do not have any special symptom or physical sign in early stages.It is easy to be delayed for diagnosis and it is often very serious when the disease was diagnosised.With the development of technology of molecular biology,the biliary tract malignant tumours' diagnosis in molecular biology has been made some progresses,and it is expected to be possible to diagnose and treat the diseases in early stages.

CD36 is involved not only in the metabolism of lipids,but also in the inflammatory reaction,in the formation of foam cells and in the pathogenesis of atherosclerosis.Monocyte/macrophage CD36 has been shown to play a critical role in the development of atherosclerotic lesions by its capacity to bind and en-docytose oxidized low density lipoproteins(oxLDL),and it is implicated in the formation of foam cells.CD36 expression and regulation mechanism already provides a new understanding and the relevant drug research has attracted more attention of scholars.This article is to carefully review the importance of CD36 as an essential component in the pathogenesis of atherosclerosis.

The research of induced phripotent stem(ips)cells is a hotspot in the area of life sciences at present.Currently,the research of ips cells has focused on cells'induction methods,source and differentiation.At the same time,the research of ips cells'application has also made some achievements.With the extensive research of application,ips cells will have an inestimable effect on the future of biomedical development.This article will give an reviews the latest application and future research trends of ips cells.
